Abstract

REATOR ANAERóBIO PARA A REMOçãO DE áCIDOS GRAXOS DE CADEIA LONGA DE áGUAS RESIDUAIS CONTENDO GORDURAS. A invenção apresentada é um aparelho projetado especificamente para o tratamento anaeróbio de alta carga de águas residuais com concentrações relativamente elevadas de compostos lipídicos, referido como "Reator Anaeróbio de Manta de Lamas Invertido" (IASB, acrónimo de Inverted Anaerobic Sludge Blanket) . Contrariamente aos reatores anaeróbios convencionais, este reator elimina a necessidade de lamas biológicas com boa capacidade de sedimentação e explora o problema da flutuação das lamas devido à adsorção de ácidos graxos de Cadeia Longa (AGCL) ou biogás nas lamas e/ou na encapsulação do biogás nas lamas. Além disso, proporciona um aumento da área superficial específica das lamas para uma melhor degradação dos AGCL. A alimentação do reator é realizada na parte superior do mesmo, sendo a separação de fases realizada na base do reator. Os conteúdos do reator são devidamente misturados através da nova ação combinada de um efeito de "gás-lift" e de um reciclo de líquido no interior do reator O reator pode operar em modo contínuo ou sequencial. Embora seja especificamente projetado para a degradação de lípidos a sua aplicação não se encontra limitada a este tipo de efluentes.ANAEROBIC REACTOR FOR THE REMOVAL OF WASTE LONG CHAIN FATTY ACIDS CONTAINING FATS. The present invention is an apparatus specifically designed for the high anaerobic treatment of wastewater with relatively high concentrations of lipid compounds, referred to as "Inverted Anaerobic Sludge Blanket" (IASB). Unlike conventional anaerobic reactors, this reactor eliminates the need for well-settling biological sludge and explores the problem of sludge fluctuation due to adsorption of Long Chain Fatty Acids (LCFA) or biogas in sludge and / or biogas encapsulation in the mud. In addition, it provides an increase in sludge-specific surface area for better degradation of LCFA. The reactor is supplied at the top of the reactor, with phase separation at the base of the reactor. Reactor contents are properly mixed through the new combined action of a gas lift effect and a liquid recycle inside the reactor. The reactor can operate in continuous or sequential mode. Although specifically designed for lipid degradation, its application is not limited to this type of effluent.
